ILMPROVEMKENi-"IN 'RECTIFYING APPARATUS.

Specification forming-part of Letters Patent No. 137,428, dated November 20, 1877i application filed v v August'QB, 1877.

To cllwhom t maytoaccm:V A Y Be it known, that I, JOHN HENRY THIER- vMAN, of Louisville, in the `county of J efferson.- and State of Kentucky, have invented certain; new and useful Improvements in/Bectifying Apparatus, and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled 'in the -art to whichit appertains to make and use the same, reference being had to the accompanying drawings, whichform a part of this specifica-V tion, and in4 which- Figure 1 is a vertical section of the rectify- .ing-cylinder, and Fig. 2 is a side view of a se! ries of cylinders in the process of rectification.

Similar letters of reference indicate corrematerial, and provided with a perforated false bottom, b, raised-upon supporting-bridges b' b'. On'top of this I place a woolen blanket,

. a, stretched and pressed closely against the inner walls of the cylinder by a ring, c, of copper wire or other suitable material. al a2 are two other similar blankets, held by rings c1 c2, resting upon shoulders or brackets d upon the inner walls of the cylinder. This latter is thus divided into three compartments, B B B, each of which 'is lled with a packing of ordinary rectifying-charcoal.

Above, and resting upon a blanket, a3, 4which. covers the charcoal in the upper chamber B, I place a cover or partition of perforated sheet metal, C, having a central upwardly-projecting cylinder, D, forming a chamber, the sides of which are perforated, as shown. This chainber, which is filled with a packing of raw cotton, reaches to the top or head of the cylinder, which forms its cover and serves as a brace to support the partition C. The blanket a3, which is spread ontop of the charcoal in the upper chamber B, is held in place by the partition C, which is braced in its place firmly by the top or head of the cylinder, and which, together with the cotton, prevents the ne particles of charcoal from passing from the cylinder. F is the top or head of the cylinder, having a circumferential flange, e, corresponding with a similar flange, c', at the top of the cylinder proper. Below this flange I place a rin g, f, of iron or other suitable metal, the edge of which projects beyond the flange, After placing the head upon the cylinder, a packing-ring, z', of rubber -or similar material, being interposed, I adjust a ring, f', similar to f, over the iiangee. The rings fj" have perforations for bolts g g, by which'they are united, thus securing the cover upon the cylinder.` There being no perforations or bolt-holes in the flanges e e the cover fits absolutely tight.`

The cover F has a central perforation, from which the exit-pipe Gr conducts the liquor .out

of the cylinder. A convex screen or sieve, g', covering this perforation, prevents the cotton packing in chamber D from entering. and choking up the exit-pipe G. A cock, h, is arranged Aupon pipe G to permit the escape of air fromy the cylinder when necessary. y

H is the induction-pipe. It enters the cylinder below the false bottom b, and is provided with a cock, k, for regulating the iiow of liquor. Z is a cock arranged below the false bottom b for drawing off the contents of the cylinder Awhich remain after disconnecting. In the process of rectifying I employ three cylinders, all constructed alike, and I keep a fourth cylinder as a reserve to take theplace of the one to be rinsed and repacked. All the cylinders are mounted on platforms and rotating trucks K, so as to enable them to be -readily shifted about.

In operation, the three cylinders A1 A2 A3 are placed beside each other, asy shown in the drawings, Fig. 2.' The first one is connected by a pipe, P, with the reservoir It, which is located upon an upper iioor. The exit-pipe of Al is connected with the induction-pipe of A2, and the exit-pipe of A2 with the inductionpipe of A3. The exit-pipe of the latter is'connected by a pipe, P, having an observing glass, O, with the receiving and storing tank B', located preferably on a lower iioor. The connecting-pipes P2 P2 are .provided with couplings p p, which enable the cylinders to be readily disconnected.

charcoal from passing oilI with the liquor.`

When the partition C at the top is reached the liquor passes into the chamber D, through the cotton, and lout through the exit-pipe, from whence it is conducted to the bottom lof the next cylinder, where the same process is repeated. From the third or last cylinder the 'liquor is conducted to the receiving-tank in a thoroughlyY cleansed and rectified state.

After the packings in cylinder A1 have be come impregnated with impurities the cylin-` der is disconnected, the liquor remaining in it drawn off through cock l, and the cylinder is rinsed by forcing water through it, and thus until the rinsings (which are conducted to a rinse-receiver) cease to show liquor impregnaafter which the foul packings are discarded, and fresh and clean ones supplied. The reserve cylinder is meanwhile brought into use. I change the position lof cylinder A3 to the former position of A1, A2 to A3, and the reserve cylinder, being freshly packed, Iplace in the original position of A2, thus preventing the liquor, when rectification is resumed, from carrying with it from the newly-packed cylinder immediately to the receiving-tank R' any fine particles of charcoal whichmight injure' its color or gloss. When the cylinder now having the original position of A1 has become foul, cylinder A1 having been rinsed, emptied,l and repacked, the same relative changes of positions are effected as described, the newlypacked cylinder being thus' always. placed in` the original position of A2.

rlhe pipe-couplings p p are so constructed as to render the cylinders easy of connection or' disconnection, and,'the cylinders being permanently mounted on trucks, as described, they can be--easily manipulated and placed in any desired position.

I do not broadly claim the perforated diaphragms and dividing blankets herein described, being aware that these, broadly considered, are old; but

Having thus described my invention, I claim and desire to secure by Letters Patent of the United Statesl. The cylinder A, having brackets d d, in combination with the blankets al a? and wire rings c c2, by` which itis divided into several compartments, B B, substantially as and forthe purpose herein shown and specified.

2p. The combination of the rectifying-cylinfderA, having circumferential flange e', perforated top partition C, having a central per'- forated cotton chamber, D, and top-piece F, having flanged screen or sieve g fitting over the chamber D, and annular flange e, all constructedv and combined so as to form an open annular chamber in the top of cylinder A, surrounding the cotton-chamber D, substantially as and for the purpose herein shown land specified.

3. As an improvement in rectifying apparatus, the interchangeable cylinders A1 A2 A, 'mounted en trucks and provided with induc- ,tion-pipes H, and exit-pipes Gr, provided with couplings p p p, substantially as and forthe purpose herein shown and specified.

In testimony that I lclaim the foregoing as my own' I have hereto afxed my signature in presence of two witnesses. i
